Product details
Overview
SMA5J6.0CA-E3/5A from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR at 10 mA), 500 W peak pulse power (10/1000 μs), clamping voltage of 10.3 V at 48.5 A, and operates from –55 °C to +150 °C junction temperature - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J6.0CA-E3/5A datasheet, SMA5J6.0CA-E3/5A pinout, SMA5J6.0CA-E3/5A application, or SMA5J6.0CA-E3/5A equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM = 1.72), AEC-Q101 qualification eligibility (via HE3/HM3 variants), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ps) to ESD and lightning-induced transients. Its bidirectional architecture enables symmetrical clamping without polarity sensitivity, supporting both AC-coupled and floating-line protection schemes.
The device delivers 500 W peak pulse power under standardized 10/1000 μs waveform conditions, with thermal resistance RθJA = 80 °C/W and RθJL = 25 °C/W - enabling reliable operation in compact PCB layouts when mounted per recommended pad dimensions (0.2" × 0.2").
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 5 V logic or CAN bus lines. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - verified breakdown threshold ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 10.3 V at 48.5 A - clamping voltage limits downstream IC stress during 500 W surge; clamping ratio = 1.72. |
| PPPM | 500 W - peak pulse power rating per 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 (4 kV) compliance with proper layout. |
| Junction Temp Range | –55 °C to +150 °C - enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| Package | SMA (DO-214AC) - surface-mount package with 5.28 mm × 4.50 mm footprint, MSL level 1, lead-free matte tin terminations. |
Pinout & Package
SMA5J6.0CA-E3/5A is housed in an SMA (DO-214AC) package - a two-terminal, non-polarized surface-mount case with no cathode marking (bidirectional configuration). Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 class 2 whisker test requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient conduction path | No polarity marking required; either terminal serves as input/output for AC or floating signals - simplifies layout and eliminates orientation errors. |
| Case (body) | Thermal and mechanical interface | Plastic body meets UL 94 V-0 flammability rating; thermal path to PCB copper via soldered terminals - requires 5.0 mm × 5.0 mm pads per terminal for rated power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled lines (e.g., RS-485, CAN FD differential pairs) without external polarity management. |
| Low clamping ratio (VC/VWM) | 1.72 - minimizes voltage overshoot across protected ICs, reducing risk of latch-up or gate oxide damage in 5 V systems. |
| Fast response time | <1 ps - suppresses ESD (IEC 61000-4-2 ±15 kV contact) and fast-rising transients before sensitive circuitry reacts. |
| AEC-Q101 qualification path | Available in HE3/HM3 variants - supports automotive-grade sourcing for engine control modules and ADAS sensor interfaces. |
| Automated placement compatibility | Low-profile SMA package with J-STD-020 MSL level 1 - compatible with standard SMT pick-and-place and reflow profiles (peak 260 °C). |

Use Scenario: Adding secondary-level surge protection on USB 2.0 D+/D− lines downstream of primary ESD diodes in portable devices. IC Role / Device Role / Timing Role: High-power backup suppressor activated only during sustained overvoltage (e.g., hot-plug inductive kick), complementing low-capacitance ESD arrays. Use Value: Extends system-level robustness beyond IEC 61000-4-2 to include IEC 61000-4-5 surge immunity without degrading 480 Mbps data rate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0CA | Lower PPPM (400 W vs. 500 W); same VWM, VBR, and package; higher clamping voltage (10.5 V). | Limited to lower-energy threats (IEC 61000-4-5 Level 3); less margin for 24 V industrial transients. | Select SMAJ6.0CA only if system-level surge testing confirms 400 W sufficiency and cost optimization is prioritized. |
| SMBJ6.0CA | Same electrical specs but SMB (DO-214AA) package - 30 % larger footprint (4.57 mm × 3.94 mm) and higher RθJA (100 °C/W). | Requires more PCB area; reduced power density limits use in space-constrained automotive modules. | Choose SMBJ6.0CA only when existing layout accommodates SMB pads or thermal derating allows 500 W operation at elevated ambient. |
Compared with SMAJ6.0CA and SMBJ6.0CA, SMA5J6.0CA-E3/5A delivers superior power density (500 W in smallest footprint), tighter clamping (10.3 V), and direct compatibility with high-volume SMT lines - making it optimal for next-generation automotive and industrial edge nodes where size, performance, and process yield are jointly constrained.

FAQ
What is the clamping voltage of SMA5J6.0CA-E3/5A at its rated peak pulse current?
The SMA5J6.0CA-E3/5A has a maximum clamping voltage (VC) of 10.3 V when subjected to its peak pulse current (IPPM) of 48.5 A under the standard 10/1000 μs waveform. This value is measured at TA = 25 °C with devices mounted on 0.2" × 0.2" copper pads per terminal, and directly determines the maximum voltage stress imposed on downstream circuitry during surge events.
Is SMA5J6.0CA-E3/5A suitable for automotive applications?
SMA5J6.0CA-E3/5A itself is commercial-grade (RoHS-compliant, E3 suffix), but Vishay offers AEC-Q101 qualified versions under HE3 and HM3 suffixes (e.g., SMA5J6.0CAHE3_A). The SMA5J6.0CA-E3/5A shares identical electrical and thermal characteristics with those qualified variants - enabling seamless qualification migration once automotive design validation is complete.
How does the bidirectional design of SMA5J6.0CA-E3/5A affect its PCB layout?
The SMA5J6.0CA-E3/5A has no polarity marking and functions identically regardless of terminal orientation, eliminating orientation checks during assembly and allowing flexible placement on differential or AC-coupled traces. Its SMA (DO-214AC) package requires symmetric 5.0 mm × 5.0 mm copper pads per terminal to sustain full 500 W pulse power - unlike unidirectional variants that require cathode alignment.
What is the thermal resistance of SMA5J6.0CA-E3/5A, and how does it impact power handling?
SMA5J6.0CA-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead (RθJL) of 25 °C/W. These values assume mounting on minimum recommended pad layout; exceeding ambient temperatures above 25 °C requires derating per Figure 2 in Vishay document 88875 - e.g., at 85 °C ambient, maximum sustainable PPPM drops to ~350 W for reliable operation.
Does SMA5J6.0CA-E3/5A meet industry surge immunity standards out of the box?
SMA5J6.0CA-E3/5A provides the core clamping performance needed for IEC 61000-4-5 (surge) and IEC 61000-4-2 (ESD) compliance, but system-level pass/fail depends on PCB layout - including trace length, grounding, and proximity to protected ICs. Vishay specifies that 500 W rating applies with 0.2" × 0.2" copper pads; achieving Level 4 (4 kV) requires adherence to this layout and supplementary filtering where necessary.
